Hello all, have a new 1.5Kw VFD that when setup and configured will not run the motor. I get a bump and then a code OC -u, which is acceleration over current or component failure. I suspect the later. I've checked the motor, 2.2 ohm phase to phase, no leakage to ground. It's a used century 2 hp. 1750 wired for 220, yes I verified that. Set acceleration parameter to as high as 90 sec., still no joy. Watched current with a fluke 87 and an amp clamp, peak current capture was only .75 amp during the start attempt. If anyone has run into this and found some parameter that fixes this I'd greatly appreciate enlightenment.
